Explanatory Note

We are filing this Amendment No. 1 on Form 10-Q/A (“Form 10-Q/A”) to our Quarterly Report on Form 10-Q for the quarterly period ended October 1, 2011, filed with the Securities and Exchange Commission on November 15, 2011 (the “Form 10-Q”), solely to furnish Exhibit 101 to the Form 10-Q in accordance with Rule 405 of Regulation S-T. Exhibit 101 to this report provides the consolidated financial statements and related notes from the Form 10-Q formatted in XBRL (eXtensible Business Reporting Language).

This amendment includes new certifications by our Chairwoman of the Board and Chief Executive Officer and our Interim Chief Financial Officer pursuant to Sections 302 and 906 of the Sarbanes-Oxley Act of 2002, filed as Exhibits 31.1, 31.2, 32.1 and 32.2 hereto. Each certification as corrected was true and correct as of the date of filing of the Form 10-Q.

No other changes have been made to the Form 10-Q. This Amendment No. 1 to the Form 10-Q does not reflect events that may have occurred subsequent to the date of filing of the Form 10-Q or modify or update in any way disclosures affected by subsequent events. Consequently, all other information not affected by the corrections described above is unchanged and reflects the disclosures made at the date of the filing of the Form 10-Q and should be read in conjunction with our filings with the SEC subsequent to the filing of the Form 10-Q, if any.

Pursuant to Rule 406T of Regulation S-T, the interactive data files on Exhibit 101 hereto are deemed not filed or part of a registration statement or prospectus for purposes of Sections 11 or 12 of the Securities Act of 1933, as amended, are deemed not filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, and otherwise are not subject to liability under those sections.
